Feed Drive System

Outline

This puncher unit is installed in the feed inlet unit inside the finisher. It punches holes in paper fed from the host machine according
to the puncher controller PCB instructions. Paper feeding inside the puncher unit is performed by the delivery roller of the upstream
connection machine and the inlet roller of the finisher. In the paper feed path, there are the punch inlet sensor (PS301) and punch
horizontal registration sensor (PBA301/PBA302), which detect the paper feed status and the horizontal registration position,
respectively.
